Pôr do Sol, Brazil

With a population of over 101,866, this administrative region in the Federal District is one of the largest informal settlements in the country. The area was a rural backwater until the 1990s, when rapid, unplanned growth led to years of minimal infrastructure and substandard living conditions. While some progress has been made in regularizing land titles and improving services, bureaucracy remains a persistent headache. This is not the picturesque, well-planned Brazil that many expats dream of - Pôr do Sol is a gritty urban sprawl for those willing to navigate its challenges.
